C++: Making A Simple Game
Putting Things Together
This lesson is basically going to bring a lot of the things we learnt in previous lessons together to make a very basic (and very messy and overcomplicated) game. When I first planned this lesson I thought I would walk you through how I created the game, however now I'm thinking about it I will only give you a brief explanation on how I did it, as I know that if you have read through all the previous lessons you know how its all done.
Here is the code for the basic game:

DownloadAs you can see that is a LOT of coding. However it really isnt that complex; In all honesty all I did to create this game is come up with a basic idea, and then start trying to create it with techniques I knew. Half of the code that I started with has either been changed of wiped out in the process of creating my game, as I saw functionality flaws etc. But when I had removed code it was only because I had a better coding idea to replace that one. Also note that I have used system functions, which is unadvised; It would be more suggested to use something like "cin.get()" instead of "system("PAUSE");", there are also other alternatives to the "system("cls");" function.
The program also has many other problems which is why I do not class it as a complete game.
I started of with a system based of bool's in which there was a bool (controlled by a class member function) for the customers order, and a bool for what the user put in; However I then later found that it would be much easier just to check the values the user typed in.
Then I had a notepad for day or two and just came up with more functionality ideas (remember a notepad and pen is your best friend), then I wrote a bit more code (with some quite complex if statements) and seemed to come up with a pretty good basis for the game.
Then I searched around for a while for ways of measuring time, and decided to use ctime as it seemed to be one of the easiest ways, as the ctime clock() function seemed to make it very easy to check the current "time".
After that I was just coding for a day or two to get everything working and to add and remove new features I decided I might add.
Thats about it, thats all I really did. Remember this is not a complete game, its what I would call a "simple game" its sort of a game, yet its not quite got absolutely everything correct and perfected; In fact I suggest you get the code, mess around with it a bit, and then if you come up with a good alternative post it in the forums (release section).
I also suggest you do a little project like this yourself, the hardest bit is actually coming up with an idea! Just get a notepad and pen, sit down for a while and write some ideas then start the basic draft coding!
NOTE: This game is VERY messy, more than anything its just to show you the basic idea of a game loop (which will be covered more in the win32 C++ section).
